A backlight assembly comprises: a receptacle; a support frame; and a light source module. The support frame is arranged on one side of the receptacle. The light source module is accommodated in the support frame and includes a printed circuit board and light sources. The support frame includes: a bottom portion; a side wall portion; a cover portion; a gap holding portion; and an insertion groove. The side wall portion extends from the bottom portion. The cover portion extends from the side wall portion to an inside. The gap holding portion extends from an end portion of the cover portion in a direction of the bottom portion. The printed circuit board is partially inserted into the insertion groove to be arranged on the upper surface of the bottom portion. The light sources are surrounded by the side wall portion, the cover portion, and the gap holding portion.

Backlight assembly having support frame

A backlight unit includes a light source portion configured to provide light to a display panel, a reflection sheet arranged on a lower part of the light source portion, a mold frame accommodating the light source portion, and a support frame which supports the mold frame and includes a bottom portion, first and second side wall portions which extend upward from both end sides of the bottom portion and face each other, a ceiling portion which extends in a horizontal direction from an upper end of the first side wall portion, and a slant portion slanted downward from an end part of the ceiling portion and having one end that comes in contact with the end part of the ceiling portion and the other end that comes in contact with an upper end of the second side wall portion.

Backlight unit and liquid crystal display including the same

A display device includes: a display panel; a bottom container member which receives the display panel; an auxiliary member including a bottom, and a side extending from an edge of the bottom, and coupled with the bottom container member; a light source unit coupled with the side of the auxiliary member; and a first heat radiating member between the auxiliary member and the light source unit. The first heat radiating member includes a phase change material.
